The Key Benefits of an Angle Conversion Calculator

Understanding angles and how to measure different angles typically begins in the 4th grade and continues till high school or college or your further studies. Despite this, it is easy to miss the use of angles in everyday life although angles are used in almost every job and in the majority of the things we do. Measuring angles is considered an easy task but converting them in different units is something really difficult. In order to make it easy for you to convert angles into different units more conveniently, we present the best online angle conversion calculator that allows you to convert different units of angles in the blink of an eye.

Using an angle conversion calculator would be more efficient if you understand the angle and its properties first. So, let's take a look at the angle and different terminologies related to it.

What is the angle?

In geometry, an angle is defined as the figure that is formed by two rays that are meeting at a common point. We can also define an angle as the degree of elevation. An angle may be represented as '∠'.

Terminologies in angles

We always measure an angle in an anticlockwise manner. Here are some of the terminologies related to angles-

  1. Vertex- a vertex is a common point in an angle at which two rays meet each other in order to form an angle.
  2. Arms- the rays that form an angle from a fixed point are known as the arms of an angle.
  3. Measuring angles- in order to measure angles, we place the centre of a protractor at a fixed point at one arm of the angle. The second arm shows the measurement of the angle in degrees.

Different types of angles

  1. Zero angle- all angles which measure is 0 degree are known as zero angles. It simply means that the final and initial arms of an angle lie on one another.
  2. Acute angle- all angles whose measurement is less than 90 degrees but more than 0 degrees are known as acute angles.
  3. Right angles- an angle whose measurement is 90 degrees is known as a right angle. In this angle, one arm is perpendicular to the other.
  4. Obtuse angle- an angle whose measurement is greater than 90 degrees but less than 180 degrees is said to be an obtuse angle.
  5. Straight angle- an angle is said to be a straight angle if it is equal to 180 degrees.
  6. Reflex angle- an angle whose measurement is greater than 180 degrees but less than 360 degrees is called a reflex angle.
  7. Complete angle- an angle whose measurement is 360 degrees is called a complete angle. In this case, the other arm of the angle makes one complete revolution and returns to the starting position.

Different types of angle units

Arcminute [ MOA ]

Arcminute or minute is a unit of angle measurement whose value is equal to 1/60 degree or 60 arcseconds.

Arcsecond [ arcsec ]

The value of one seconds or arcsecond is equal to 1/60 minute.

Degree [ ° ]

A degree is known to be the standard unit of angle measurement whose value is equal to 60 minutes, 3600 seconds or 1/360 circle.

Full circle

It is a traditional unit of the plane angle whose value is equal to 360 degrees.


The value of a quadrant is equal to 90 degrees or ¼ of a full circle.


Radian is a unit of angle measurement which is majorly used in science and mathematics. Its value is equal to 57.295779° or 1/(2 pi).

Angles we encounter in our daily life

We encounter numerous angles in our daily life yet we pay very little attention to them. We discussed some of the examples of angles in real life such as the arms of a clock, the edges of a table, etc. the most common use of angles is in the field of architecture. If you are building a rectangular room, you need angles. Angles are used in making blueprints, diagrams and various other things.

Angles in math is typically an easy task but becomes more difficult when measuring angles. The difficult part starts when you are asked to convert those angles into different units. This is the time when the angle conversion calculator is useful as it can complete the conversions for you or you can use it to check that you have converted the angle correctly.


Although you could do all the calculations related to angles on your own (manually), using this online angle conversion calculator is highly recommended to professionals whose work involves frequent angle conversion. A conversion calculator makes it easier and saves a lot of time.

It is very easy to use and offers you solutions within seconds. All you need to do is select the value that you want to convert, the unit of that value, and the unit that you want as the final answer.
